I have no problem paying for extra tanks in some cases ... I like having some sort of redundant air when I dive, as I enjoy taking pictures and will not always be within 30 seconds of someone. That's the reality of UW photography.
Aside from solving my "air-hog" problem, .
An additional benefit of sidemount. For people who go through air faster, they are able to stay with the rest of the group longer, and that should make everyone happy.
Also, with sidemount, we don't need a tec operation for support. Sure, we won't have a left handed valve, but we can all deal with that.
Seeing that you list Seattle as a location, have you ever gone diving with Bill Minton's charter out on Neah Bay? Recently we dove the Diamond Knot and I was in sidemount. I had no trouble climbing up the ladder in some swell with 20 lbs of lead and 2 S100 tanks. I'd imagine that on a LoB in a wetsuit, a lot less lead (maybe none?), and 2 AL80's, I'll have a much easier time.I silently question the merits of sidemount on a LoB - mostly due to sea conditions. With a 1 to 1.5 m swell in the south China Sea, getting up a ladder on the stern of a large LoB is difficult. As a guide with a great crew, it sometimes takes one person in the water, and one person on the deck to assist a sidemount diver to board the boat. Its safe, but might be inappropriate for the conditions.
